Apparatus and process for analyzing a stream of fluid

Abstract

An analyzing probe for insertion into numerous different environments to determine at least one characteristic of particulate matter suspended in a fluid stream of a test sample. Preferably, the analyzing probe includes a minimal amount of optical elements such as lenses that are subjected to the conditions of the environment of the fluid stream to be tested. Further, the analyzing probe is preferably designed so that it can be readily manufactured, operated and installed by relatively unskilled laborers.

Description

[0001] The present invention is directed to devices and processes used to detect particles in a fluid (i.e., liquid or gas) stream. More specifically, a fluid stream to be tested is subjected to electromagnetic radiation at a sensing region. Particles in the fluid stream cause the electromagnetic radiation to scatter. The electromagnetic radiation affected by the particles in the fluid stream being tested is processed to identify characteristics of the particles including but not limited to particle size, type, distribution and / or concentration.[0002] Various devices have been used to test fluid streams to determine characteristics of particles in the fluid stream including particle size, type, distribution or concentration. These devices typically include a light source for generating electromagnetic radiation with a particular wavelength and an optical coupler for transmitting the light to a sensing region. The light illuminating the fluid stream is scattered by the particles susp...

Problems solved by technology

The complexity of these prior known devices has necessitated the use of very skilled laborers to manufacture, operate and deploy known particle analyzers to analyze particles in a given fluid stream.

These prior devices are disadvantageous, inter alia, because the remote location of the scattering region or chamber makes it more difficult to control and monitor the test fluid and the light used to irradiate the test fluid.

Accordingly, the complexity and expense of the analyzing system is disadvantageously increased.

Prior known particle analyzers have suffered greatly in accuracy and durability due to their deployment in hazardous test environments.

Such hazardous environments subject the particle analyzer to extremely high pressures, temperatures and / or highly corrosive conditions.

By deploying optical elements directly into the hazardous environment, the accuracy and durability of the prior known particle analyzers have been compromised.

These constructions are disadvantageous because the additional component requires further adaptation of the environment in which the particle analyzer is deployed.

Moreover, the additional component adds to the complexity and expense of the particle analyzer.
